<pre>The issue occurs with both xv and gl but I use xv by default.
I don't have the issue with a sandy bridge machine at all, only with
skylake. I see the issue in 30fps content too. Pause and unpause does
not fix here. Frame dropping is disabled in mplayer.
This is KDE desktop environment on all test machines, including the
sandy bridge one.
I tried running X directly from console with 'startx' on the problem
skylake machine and now the jerkiness is gone with mplayer. Instead,
sometimes xv playback has constant horizontal tear which goes away with
pause / unpause. With gl there is no tear.
Although there is no major jerkiness anymore without KDE I think
playback is still not quite as smooth as with Windows but it is usable.</pre>
